Paddy fish farming, also known as "rice bottom fish", is one of the traditional farmland production methods in the mountainous and hilly areas of southern my country. It is a set of excellent farmland ecology created by the working people of our country after long-term practice. system.
my country’s traditional agriculture is mainly based on the application of organic fertilizers, such as human and animal manure, rice straw, green manure, etc. When organic fertilizers are applied to paddy fields, they will breed many microorganisms and plankton, which are good feed for fish. . When fish are raised in rice fields, the fish feed on plankton and weeds in the field. Not only can the fish compete less with the rice for fertilizer, but the fish's feces and food residues also become organic fertilizers for the rice. In this way, the rice fields raise fish and fish raise rice, and the rice fields become "fish and rice fields."
In rice field fish farming, fish prey on pests living in or falling into the water, reducing the harm of pests to rice, reducing the amount of chemical pesticides, thereby reducing the pollution of the farmland environment. Therefore, fish farming in rice fields is also a measure of biological control, which plays a role in improving the farmland environment and maintaining ecological balance.
